My business has thousands of online reviews with Google etc and avg 4.7 and above. On Checkbook.org 32 reviews and avg 1 star. Clearly not an accurate review service.
Tip for consumers: Appears this business is pay to play. If you pay to be in their book, you can get solid rating. If you don't, it would clearly appear they inaccurately rate your business very low. Their ratings don't even closely reflect reality of my business ratings from all other major review services. Form your own opinion of their accuracy.
